INSTALLATION
3.7L V-6
The Throttle Position Sensor (TPS) (1) is mounted to
the throttle body.
The throttle shaft end of throttle body slides into a
socket in TPS. The TPS must be installed so that it
can be rotated a few degrees. (If sensor will not
rotate, install sensor with throttle shaft on other side of
socket tangs). The TPS will be under slight tension
when rotated.
1. Install TPS and retaining screws.
2. Tighten screws to 7 Nꞏm (60 in. lbs.) torque.
3. Connect TPS electrical connector to TPS.
4. Manually operate throttle (by hand) to check for
any TPS binding before starting engine.
5. Install air cleaner tube to throttle body.

4.7L V-8
The throttle shaft end of throttle body (5) slides into a
socket in TPS. The TPS must be installed so that it
can be rotated a few degrees. If sensor will not rotate,
install sensor with throttle shaft on other side of socket
tangs. The TPS will be under slight tension when
rotated.
1. Install TPS and two retaining bolts.
2. Tighten bolts to 7 Nꞏm (60 in. lbs.) torque.
3. Manually operate throttle control lever by hand to
check for any binding of TPS.
4. Connect TPS electrical connector to TPS.
5. Install air duct/air box to throttle body.

WARNING: The fuel injection pump supplies extremely high fuel pressure toeach individual injector
through the high-pressure lines. Fuel under this amount of pressure can penetrate the skin and cause per-
sonal injury. Wear safety goggles and adequate protective clothing. Do not loosen fuel fittings while engine
is running.
WARNING: Engine may start while cranking starter motor.
DRAINING FUEL TANK - DIESEL
Due to a one-way check valve installed into the fuel fill opening fitting atthe tank, the tank cannot be drained con-
ventionally at the fill cap.
1. Raise vehicle.
2. If vehicle is equipped with 4 doors and a 6 foot (short) box, remove left-rear tire/wheel.
3. Thoroughly clean area at top of fuel tank around fuel tank module.
4. Loosen clamp and disconnect rubber fuel fill hose at tank.
5. Drain fuel tank by attaching drain hose from an approved diesel fuel draining station to the fuel fill fitting of tank.
